D G Emission Monitoring

D G Emission Monitoring Services

Diesel generators (DG sets) are widely used in industries, hospitals and commercial facilities, but their emissions can be highly toxic. Through DG stack monitoring, organizations can measure and control the release of pollutants such as carbon monoxide, nitrogen oxides, particulate matter and hydrocarbons into the air.

Regular stack monitoring of DG sets is essential to meeting CPCB guidelines for DG stack monitoring, protecting public health, and optimising diesel usage. Equinox Labs helps industries stay compliant through real-time, accurate and fully documented DG stack emission testing services.

Why DG Stack Monitoring Matters

Why DG Stack Monitoring Matters

DG sets ensure uninterrupted power, but their byproducts, when left unchecked, can cause serious damage to health, air quality and regulatory credibility. That’s why DG stack monitoring is crucial for:

CPCB Compliance

Keeps emissions within limits mandated by the Central Pollution Control Board.

Regulatory Protection

Prevents fines and legal action by showcasing environmental responsibility.

ESG & CSR Reporting

Supports sustainability goals and transparent environmental disclosures.

Community Safety

Reduces air pollution risks for nearby residential and commercial
areas.

Fuel & Cost Efficiency

Improves generator performance while cutting down fuel usage and expenses.

Know the essential tests to ensure safety and efficiency of diesel generators.

  • Fuel quality test
  • Emission checks
  • Load test
  • Noise level assessment

Pollutants Released from Diesel Generators

During operation, DG sets emit multiple harmful substances that contribute to air pollution. These include:

Arsenic
Benzene
Nitrogen Dioxide (NO₂)
Carbon Monoxide (CO)
Hydrocarbons (HC)
Fine Particulate Matter (PM2.5, PM10)

These pollutants are measured during a DG stack emission test to ensure they remain within regulated thresholds.

Health & Environmental Impacts

Health & Environmental Impacts

The risks of unchecked emissions from diesel generators are well-documented:

Respiratory Illnesses

Nitrogen Oxide triggers asthma, lung infections, and chronic respiratory conditions.

Oxygen Disruption

Carbon Monoxide reduces oxygen flow, leading to dizziness, fatigue, and confusion.

Cardiopulmonary Damage

Particulate Matter affects both lung and heart function by reaching deep tissue layers.

Cancer Risk

Exposure to hydrocarbons and benzene is linked to elevated cancer potential.

Climate Impact

Excess Carbon Dioxide from DGs contributes to global warming and disrupts climate balance.

CPCB Guidelines for DG Stack Monitoring

CPCB Guidelines for DG Stack Monitoring

The risks of unchecked emissions from diesel generators are well-documented:

Approved Equipment Only

Emissions must be measured using CPCB-approved stack monitoring tools.

Scheduled Submissions

Test results must be reported periodically for regulatory
compliance.

Comprehensive Parameter Testing

Monitoring should cover SO₂, NOx, PM, and Carbon Monoxide
levels.

Mandatory Corrective Action

If limits are exceeded, industries must implement filters or adopt cleaner tech.

At Equinox Labs, we ensure all DG stack monitoring reports are fully CPCB-compliant and audit-ready.

Ideal Monitoring Frequency

Continuous or real-time stack monitoring of DG sets is highly recommended in sectors with high generator usage. At a minimum, testing should be conducted:

Once every quarter for compliance documentation
During the installation of new DGs or after significant maintenance
In response to public complaints or environmental audits
As part of annual ESG or CSR reports
